10273 Made in the USA, the MOE Stock Commercial-Spec Model (Magpul Original Equipment) is a drop-in replacement buttstock for AR15/M4 carbines using commercial-spec sized receiver extension tubes. Designed for light, fast action the streamlined A-frame profile avoids snagging and shields the release latch to prevent accidental activation. The Commercial-Spec Model includes an extended 0.55" thick rubber butt-pad to provide positive shoulder purchase and accommodates the longer, slanted back common to most commercial-spec tubes.
